Circuits for Ms t

This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -

• the switch gives energy to the battery

• the buzzer is made of special plastic

• the wires are cooled by the surrounding air

• electricity can flow in a complete path

What is a Series Circuit?

• A circuit with more than one path way for current to flow

• A circuit with one path way with one switch.

• An electric circuit with a single path for current to flow.

• Two circuits with one path way for current to flow

If you cut the wire right above the middle bulb, would the other two still work?

• NO!

• YES!

What is Parallel Circuit?

• A wire that has a battery and a switch.

• A circuit that contains more than one path for current flow.

• A circuit that contians one path for current flow

• A circuit with a switch

Which of the following circuit diagrams is a parallel circuit?

What happens to the brightness of the bulbs in a series circuit if more bulbs are added?

• The brightness of all bulbs increases.

• The brightness of all bulbs decreases.

• The brightness of the first bulb increases, but the rest decrease.

• The brightness of all bulbs remains the same.

In a parallel circuit, if one bulb burns out, what happens to the other bulbs?

• All other bulbs will also burn out.

• The remaining bulbs will shine brighter.

• The remaining bulbs will go out.

• The remaining bulbs will continue to shine as before.

What is the main difference between an open circuit and a closed circuit?

• An open circuit has no power source, while a closed circuit does.

• An open circuit allows electricity to flow, while a closed circuit does not.

• An open circuit does not allow electricity to flow, while a closed circuit does.

• An open circuit uses only insulators, while a closed circuit uses only conductors.
